This antigenic variation depends largely on the immune-dominant 56-kDa type-specific antigen (TSA) located on the surface of the bacteria membrane.
A novel mechanism for control of antigenic variation in the haemagglutinin gene family of Mycoplasma synoviae.
Type IV pillin in Neisseria gonorrhoeae appeared to be the best source of understanding gene conversion mechanism that further leads to antigenic variation of the mentioned pilli.
The prevalence of gastrointestinal parasitism caused by these helminthes is continuously increasing and the reason of increasing gastrointestinal parasitism is their antigenic variation. With the help of antigenic variation parasites can evade host immune response.
Thus, the 5' gC sequence differences likely explain the higher titers against homologous serum observed in this study, as well as some antigenic variation among isolates of the same species.
The European Centre for Disease Control said one of the subtypes, H3N2, has undergone genetic and antigenic variation, which could make it resistant to the flu vaccine currently on offer.
The phenomenon where parasite exhibits variable antigens on the surface of infected erythrocytes enables the parasite to endure and escape the host immune response known as antigenic variation. The symmetry of interactions between different antigenic variants can be explained by various mathematical models of antigenic variation in malaria (8).
Six variants of this serotype 1 were identified by the virus neutralization test and antigenic variation can induce failures on the vaccination processes due to the difference of antigenic structures between vaccinal and wild viruses [17, 19, 20].

Variations in the macromolecular structure of cell wall components may be at the basis of antigenic variation as well as specific host resistance to pathogens [2,6,22,32].
Typhi is a relatively invariant pathogen to antigenic variation, many of the surface antigens, therefore, may be conserved across the genera and induce antibodies that are cross reactive.
